In article number 2005159, Dong‐Pyo Kim, Hyomin Lee, and co‐workers present wax‐based Janus particles with dumbbell structures to simultaneously achieve enhanced emulsion stability and tunable thermal coalescence of these Janus particle‐stabilized emulsions. The wax‐based Janus particles enable particle‐adsorbed droplets to coalesce above a designated temperature, possessing great potential for various applications including drugs delivery, oil recovery, and micro‐reactors.
